SMIME vs PGP

[SeidlS at schneider.com]

I am not a encryption expert, and need some help from the GnuPG user group.

We have a new software product that has the capability of encrypting
documents using SMIME.  How common is SMIME and used outside of email
clients?  Is it compatible with the OpenPGP standard, and thus GnuPG?  Is
there a good website discussing the differences between the two standards?


Thanks
